The controller 100 controls the operations of the pre-processing device 10, the test device 20, and the post-processing device 50 as described above. As shown in FIG. 6, the controller 100 includes a center conveyor control unit (or only a belt control unit) 101 that controls the operation of the center conveyor 22 and an operation control of the ejector moving mechanism 45. The disengager movement control unit 103, the judging unit 105, and the alarm output unit 106. The operations of the center conveyor control unit 101, the ejector movement control unit 103, the determination unit 105, and the alarm output unit 106 are described later using a flowchart shown in the figure.

Next, the operation of the tire test system described above will be described.

When the tire T is placed on the entrance conveyor 11, the centering mechanism 12 of the pre-processing device 10 operates so that the center of the tire T is located at the center of the entrance conveyance path, in other words, on the path centerline Lc. After the centering mechanism 12 is operated, the lubricant application mechanism of the pre-processing device 10 applies the lubricant to the upper bead bead portion Tbu and the lower bead bead portion Tbd of the tire T.

When the application of the lubricant to the tire T is completed, the inlet conveyor 11 and the center conveyor 22 are driven to start, and the tire T is conveyed to the downstream side (+) X. The center conveyor control unit 101 of the controller 100 determines whether the tire T is conveyed into the reference area Br in the center conveyance path Pc from the driving amount of the center conveyor 22 or the driving time of the center conveyor 22, and the like. The center conveyor control unit 101 stops the center conveyor 22 if it determines that the tire T is within the reference area Br to the center conveyance path Pc.

When the center conveyor 22 is stopped, the belt lifting device 25 is driven to lower the center conveyor 22 and the tire T placed thereon. The upper surface of the center conveyor 22 is lowered to a position lower than the lower wheel frame 33d. During this descent process, the lower bead bead portion Tbd of the tire T is fitted into the lower wheel frame 33d installed on the lower spin shaft 31d. The tire T becomes the center conveyor 22 and the lower wheel frame 33d. Supported from below.

Here, when the center conveyor 22 is lowered, The conveying belt 22 may approach the lower wheel frame 33d, and the lowering speed of the center conveying belt 22 may be performed at a low speed. By doing so, it is possible to prevent the posture of the tire T from being disturbed.

In the process of lowering the center conveyor 22, the upper position of the center conveyor 22 and the position of the lower wheel frame 33d are almost the same in the vertical direction, and once the descending of the center conveyor 22 is stopped. By doing so, even if the tire T is unstable and swings during the descent, the tire T can be supported by both the lower wheel frame 33d and the center conveyor 22. Therefore, it is possible to suppress the wobble of the tire T, and to prevent the insertion of the tire T toward the lower wheel frame 33d.

Next, by driving the wheel frame elevator 37, the upper spin shaft 31u and the upper wheel frame 33u mounted on the upper spin shaft 31u are lowered. As a result, the upper bead bead portion Tbu of the tire T is fitted into the upper wheel frame 33u. As a result, the tire T is held by the upper wheel frame 33u and the lower wheel frame 33d. The lower part of the upper spin shaft 31u enters the lower spin shaft 31d. The upper spin shaft 31u is coupled to the lower spin shaft 31d by a locking mechanism (not shown) provided in the lower spin shaft 31d.

Thereafter, the air is supplied from the outside to the inside of the tire T through the upper spin shaft 31u or the lower spin shaft 31d. When air is supplied into the tire T, the lower spin shaft 31d rotates. With the rotation of the lower spin shaft 31d, a lower wheel frame 33d mounted on the lower spin shaft 31d, an upper spin shaft 31u coupled to the lower spin shaft 31d, and a spin mounted on the upper spin shaft 31u The upper wheel frame 33u of the shaft 31u rotates integrally with the lower spin shaft 31d. As a result, the wheels held by the upper wheel frame 33u and the lower wheel frame 33d are held. The tire T also rotates. During the rotation of the tire T, various measurements are performed on the tire T.

When the above various measurements are completed, the air is excluded from the tire T. Further, the coupling state of the upper spin shaft 31u and the lower spin shaft 31d by the lock mechanism is released. The upper spin shaft 31u whose connection state with the lower spin shaft 31d is released is raised by the drive of the wheel frame elevator 37. When the upper spin shaft 31u is retracted upward, the conveyor lifting device 25 is driven, and the center conveyor 22 is raised to the upper limit position. The tire T rises as the center conveyor 22 rises. On the other hand, the lower wheel frame 33d in which the lower bead bead portion Tbd of this tire T is fitted does not rise. Therefore, during the raising process of the tire T, the lower bead bead portion Tbd of the tire T is thereby detached from the lower wheel frame 33d. Thereafter, the plurality of tire detachers 41 are driven, the pressing plate 44 of each tire detacher 41 is brought into contact with the upper side wall of the tire T, and the tire T is pushed downward. As a result, the upper bead bead portion Tbu of the tire T is detached from the upper bead 33u. The removal of the upper wheel frame 33u of the upper bead hemming portion Tbu caused by the driving of the tire detacher 41 is also performed when the upper spin shaft 31u is performed before the center conveyor 22 is raised. can. From the above, from this tire T, the upper wheel frame 33u and the lower wheel frame 33d are pulled out.

When the upper wheel frame 33u and the lower wheel frame 33d are pulled out from the tire T, the center conveyor 22 is driven to transport the tire T on the center conveyor 22 toward the downstream side (+) X. The upper limit position of the center conveyor 22 is a position where the height of the center conveyance path Pc is the same height as the height of the entrance conveyance path and the exit conveyance path, as described above. Therefore, the center conveyor 22 The upper tire T is transferred from the center conveyor 22 toward the exit conveyor 51. The tire T is printed on the exit conveyor 51 with various information such as measurement results by a not-shown printing mechanism.

This completes the operation of the tire test system.

However, when the tire T is conveyed by the entrance conveyor 11 and the center conveyor 22, when the tire T is transferred from the entrance conveyor 11 to the center conveyor 22, the tire T may not be placed on the destination position of the center conveyor 22 . The tire T on the conveyor belt may be relatively moved with respect to the conveyor belt when the entrance conveyor belt 11 is driven to start, the center conveyor belt 22 is stopped, or the like.

If the center of the tire T is largely deviated from the aforementioned reference center Bc, the tire T may not be held by the upper wheel frame 33u and the lower wheel frame 33d. When the tire T is held by the upper wheel frame 33u and the lower wheel frame 33d, the tire T may be held in a state inclined in the horizontal direction. Therefore, when the tire T carried by the center conveyor 22 is held by the upper wheel frame 33u and the lower wheel frame 33d, it is necessary that the center of the tire T is located at almost the reference center Bc.

Here, in this embodiment, a tire conveyance method is performed in which the position of the tire T on the center conveyor 22 is adjusted. Hereinafter, this tire transportation method will be described with reference to a flowchart shown in the figure.

As described above, with the lubricant application mechanism of the pre-processing device 10, when the lubricant is applied to the upper bead bead portion Tbu and the lower bead bead portion Tbd of the tire T, the entrance conveyor 11 and the center conveyor 22 Immediately after driving, the tire T is transported to the downstream side (+) X (S1: conveyor belt) Drive starts). The center conveyor control unit 101 of the controller 100 determines whether the tire T has been transported into the reference area Br from the driving amount of the center conveyor 22 or the driving time of the center conveyor 22 as described above. The center conveyor control unit 101 stops the center conveyor 22 if it determines that the tire T has been conveyed into the reference area Br. In other words, if the tire T is transported to the reference area Br by the center conveyor control unit 101, the center conveyor 22 is stopped (S2: conveyor stop).

When the center conveyor 22 is stopped, the position sensor 60 detects the position of the tire T on the center conveyor 22 (S3: position detection process). The size of the tire T is input to the controller 100 from the outside. The release control unit 103 determines the outer diameter of the reference region Br and the outer diameter of the allowable region Ar in accordance with the size of the tire T. The detacher movement control unit 103 operates the detacher movement mechanism 45 so that each of the sensors 60ua, 60ub, 60da, and 60db is positioned vertically above the edge of the allowable area Ar determined by the size of the tire T. As a result, the first upstream position sensor 60ua is positioned on the upstream side (−) X from the reference center Bc, and is positioned vertically above the first upstream position 61ua on the edge of the allowable area Ar. The second upstream-side position sensor 60ub is located on the upstream side (-) X from the reference center Bc, and becomes vertically above the second-side position 61ub on the upstream side of the edge of the allowable area Ar. The first downstream-side position sensor 60da is located vertically downstream of the first position 61da on the downstream side of the edge of the allowable area Ar on the downstream side (+) X from the reference center Bc. The second upstream position sensor 60ub is located on the downstream side (+) X from the reference center Bc and becomes the second position on the downstream side of the edge of the allowable area Ar. 61db vertically above. If the sensors 60ua, 60ub, 60da, and 60db are located at predetermined positions, the presence of the tire T is detected by the sensors 60ua, 60ub, 60da, and 60db. In addition, the operation of the detacher moving mechanism 45 may be performed any time before the presence of the tire T is actually detected by each of the sensors 60ua, 60ub, 60da, and 60db. For example, when the tire T is present in the pre-processing device 10, the detacher moving mechanism 45 can be operated.

The determination unit 105 determines whether the position of the tire T is within the allowable range Ar based on the detection results of each of the sensors 60ua, 60ub, 60da, and 60db (S4: position determination process). For example, as shown in FIG. 7, the tire T is in the allowable area Ar, and the determination unit 105 receives the tire T from all the sensors 60ua, 60ub, 60da, and 60db as shown in FIG. 9. There is a signal for the "none" command. In this case, the determination unit 105 determines that the tire T is located in the "allowable area" based on the signals from the sensors 60ua, 60ub, 60da, and 60db. As shown in FIG. 10 and FIG. 11, the downstream (+) X portion of the tire T is outside the allowable range Ar, and the determination unit 105 is positioned from the first downstream side as shown in FIG. 9. Among the sensor 60da and the second downstream-side position sensor 60db, at least one of the downstream-side position sensors 60d has received a signal of the “yes” command existing in the tire T. In this case, the determination unit 105 determines that the “downstream side portion of the tire T is outside the allowable range” based on the signals from the sensors 60ua, 60ub, 60da, and 60db. And, at least one upstream position sensor 60u among the first upstream side position sensor 60ua and the second upstream side position sensor 60ub receives the presence of the tire T If there is a command signal of "Yes", it is determined that the "upstream side portion of the tire T is out of the allowable range".

When the determination unit 105 determines that the tire T is within the allowable range Ar, the tire T is transferred toward the reference range Br, and the tire transfer is terminated. When the tire is moved toward the reference area Br, as described above, the tire T is held by the upper wheel frame 33u and the lower wheel frame 33d, and various measurements are performed on the tire T.

On the other hand, if the determination unit 105 determines that at least a part of the tire T is outside the allowable range Ar, it determines whether or not the position adjustment process (S6) described later has been completed for this tire T (S5: adjustment presence judgment process). If the determination unit 105 determines that the tire T position adjustment process (S6) has not been performed, the center conveyor control unit 101 drives the center conveyor 22 to adjust the position of the tire T (S6: tire position adjustment process). ).

In this tire position adjustment process (S6), for example, in the position determination process (S4), if the "downstream side part of the tire T is out of the allowable area", as shown in Fig. 9, the center conveyor control The part 101 drives the center conveyor 22, and conveys the tire T on the center conveyor 22 toward the upstream side (-) X. In addition, for example, in the position determination process (S4), if it is determined that the "upstream side portion of the tire T is outside the allowable area", as shown in FIG. 9, the center conveyor control unit 101 is the center conveyor 22 Driven, the tires T on the center conveyor 22 are slightly transported toward the downstream side (+) X. The micro-driving amount of the center conveyor 22 is, for example, only 1/2 of the difference between the outer diameter of the allowable area Ar and the outer diameter of the reference area Br. The distance that the tire T moves.

When the tire T is micro-conveyed by the drive of the center conveyor 22, the position sensor 60 detects the position of the tire T on the center conveyor 22 again (S3: position detection process). Next, the determination unit 105 determines whether the position of the tire T is within the allowable range Ar based on the detection results of the sensors 60ua, 60ub, 60da, and 60db (S4: position determination process). The determination unit 105 is based on the detection results of each of the sensors 60ua, 60ub, 60da, and 60db. If it is determined that the position of the tire T is within the allowable range Ar, the tire transfer to the reference range Br ends. On the other hand, the determination unit 105 determines whether at least a part of the tire T is outside the allowable area Ar based on the detection results of each of the sensors 60ua, 60ub, 60da, and 60db. Tire position adjustment process (S6) (S5: judgment process of adjustment presence or absence). In this case, because the tire position adjustment process has been performed for this tire T (S6), the determination unit 105 determines that the tire position adjustment process has been completed for this tire T (S6).

If it is determined by the determination unit 105 that the tire T has completed the tire position adjustment process (S6), the alarm output unit 106 outputs an alarm indicating that the tire position is defective (S7: alarm output process). If the operator outputs this alarm, for example, once the operation of the tire test system is stopped, the position of the tire T on the center conveyor 22 is adjusted by itself.

As shown in FIG. 11, the tire T is deviated from the reference area Br in the tire conveying direction X and slightly in the path width direction Y. In some cases, if the center conveyor 22 is driven during the tire position adjustment process (S6), the tire T can be located in the allowable area Ar. However, as shown in FIG. 12 (a), the tire T is largely deviated from the reference area Br toward the path width direction Y. In the tire position adjustment process (S6), even if the center conveyor 22 is driven, as shown in FIG. 12 As shown in (b), there is a case where the tire T cannot be located in the allowable area Ar. In this embodiment, in this case, an alarm output process is performed (S7).

As described above, in this embodiment, the position of the tire T on the center conveyor 22 is detected after the tire T is transported to the reference area Br by the center conveyor 22. Then, it is determined whether the tire T is within the allowable area Ar with respect to the reference area Br, and if the tire T is not within the allowable area Ar, the center conveyor 22 is driven to adjust the position of the tire T. Therefore, in the present embodiment, the position of the tire T can be positioned within the allowable range Ar, and as a result, the frequency with which the tire T cannot be held by the upper wheel frame 33u and the lower wheel frame 33d can be reduced. Furthermore, in this embodiment, since the tire T can be fitted to the upper wheel frame 33u and the lower wheel frame 33d with high accuracy, the measurement of the tire T can be performed with high accuracy.

And in this embodiment, as is known in the art, a pair of guides are provided, and the pair of guides are driven without adjusting the position of the tire T, and the existing conveyor belt is driven to adjust the position of the tire T. Therefore, in this embodiment, the cost of the device can be suppressed.

Moreover, although the position detection process (S3) is performed after the center conveyor 22 is micro-driven in the tire position adjustment process (S6), the position detection process is performed after the center conveyor 22 is micro-driven. The process (S3) is also possible.

`` Second Embodiment ''

A second embodiment of the tire test system of the present invention will be described with reference to FIGS. 13 and 14.

The hardware configuration of the tire test system of this embodiment is the same as that of the tire test system of the first embodiment. On the other hand, the software configuration of the tire test system of this embodiment is different from that of the tire test system of the first embodiment.

The controller 100 of the tire conveyance device C in the first embodiment includes a center conveyor control unit 101, a separator movement control unit 103, a determination unit 105, and an alarm output unit 106. As shown in FIG. 13, the controller 100 a in the tire conveying device Ca in this embodiment includes a center conveyor control unit 101 a, a separator movement control unit 103, a determination unit 105, and an operation of moving the entrance conveyor 11.

In the first embodiment, after the tire position adjustment process (S6), the position detection process (S3) and the position determination process are performed. (S4), and the judgment process of the presence or absence of adjustment (S5). In this judgment process of the presence or absence of adjustment (S5), if it is determined that the tire T has completed the position adjustment process (S6), an alarm output process (S7) is performed.

On the other hand, in this embodiment, in this adjustment presence / absence judgment process (S5), if it is determined that the tire T has completed the position adjustment process (S6), the alarm output process (S7) may be replaced, as in the 14th step. As shown in the flowchart in the figure, the center conveyor reverse drive process (S8), the inlet conveyor reverse drive process (S9), and the centering process (S10) are performed.

In this embodiment, if it is determined that the position adjustment process (S6) has been performed for the tire T in the adjustment presence / absence determination process (S5), the center conveyor control unit 101a instructs the center conveyor 22 to perform reverse driving (S8) : Center conveyor reverse driving process), and the inlet conveyor control section 102 instructs the reverse conveyor for the inlet conveyor 11 (S9: inlet conveyor reverse driving process). As a result, the tire T on the center conveyor 22 is conveyed toward the upstream side (-) X by the reverse drive of the center conveyor 22, and is transferred to the entrance conveyor 11. The tire T transferred to the entrance conveyor 11 is further transported toward the upstream side (-) X by the reverse drive of the entrance conveyor 11. When the tire T is transported to a position where it can be centered by the centering mechanism 12 of the pre-processing device 10, the center conveyor 22 and the entrance conveyor 11 are stopped.

When the center conveyor 22 and the entrance conveyor 11 are stopped, the centering mechanism 12 is driven by the instruction from the centering control unit 104 so that the center of the tire T is located on the path centerline Lc, and the entrance is performed. Centering of the tire T on the belt 11 (S10: centering process).

When the centering process (S10) is performed, the process returns to step 1 and the processes after step 1 are performed.

In the first embodiment, as described above using FIG. 12, the tire T is largely deviated from the reference area Br in the path width direction Y. In the tire position adjustment process (S6), even if the center conveyor 22 is driven, There is a case where the tire T cannot be located in the allowable range Ar. In this embodiment, in this case, the tire T is returned to the pre-processing device 10, and the centering mechanism 12 of the pre-processing device 10 centers the tire T. Therefore, in the present embodiment, when the tire T deviates from the reference area Br in the path width direction Y, the tire T may be located in the allowable area Ar.

"Modification"

The present invention is not limited to the above-mentioned embodiments, and includes various modifications to the above-mentioned embodiments within a scope not departing from the spirit of the present invention. That is, each embodiment is only an example of a specific shape and configuration, and may be appropriately changed.

If the position sensor 60 can detect whether the tire T is located in the allowable area Ar, it is not necessary to arrange a plurality of sensors as in the above embodiment. For example, as shown in FIG. 15, only one upstream side position sensor 60u and one downstream side position sensor 60d may be provided. In this case, in order to respond to the change in the tire size, it is preferable to attach each of the position sensors 60u and 60d to the tire detacher 41. And, in this case, pass the reference center Bc, the position sensors 60c and 60c which detect the position on the dotted line extended in the path width direction Y may be added. In this case, in order to respond to a change in tire size, for example, a bracket 29 is attached to a pair of belts 23 constituting the center conveyor 22 to a belt frame supporting one of the belts 23, and a position sensor 60c is attached to This bracket 29 is preferred.

The plurality of position sensors in the above embodiments are all transmissive laser sensors. However, these sensors are, for example, reflective types. It is also possible to use a sensor that detects the distance. That is, if one or more sensors constituting the position sensor can detect whether the tire T is located within the allowable range Ar, any sensor may be used.

The tire detacher 41 of the above embodiment is a pneumatic cylinder. However, for example, if the linear actuator has a driving end that moves linearly, the tire detacher 41 may be configured by any device.

In the above-mentioned embodiment, the detacher moving mechanism 45 moves the tire detacher 41 in a horizontal direction and in a direction parallel to the path center line Lc. However, the detacher moving mechanism 45 may move the tire detacher 41 in the horizontal direction and in a direction twisted with respect to the path center line Lc. However, in this case, since the deviation position sensor 60 for the tire conveyance direction X of the tire T in the allowable range Ar is detected, it is necessary to include a component in the tire conveyance direction X in the moving direction of the tire detacher 41.

In each of the above embodiments, the center conveyor belt 22 is lowered, and the center conveyor belt 22 is relatively moved with respect to the lower wheel frame 33d. However, for example, by raising the lower wheel frame 33d, The lower wheel frame 33d may be relatively moved.

In each of the above embodiments, the tire T is first stored in the lower wheel frame 33d, and then the upper wheel frame 33u is lowered, and the tire T is inserted into the upper wheel frame 33u and the lower wheel frame 33d. However, after the tire T is deposited in the upper wheel frame 33u, the lower wheel frame 33d is brought close to the tire T, and the tire T may be inserted into the upper wheel frame 33u and the lower wheel frame 33d. That is, the configuration of the tire holding machine of the present invention is not limited to the configuration of the tire holding machine 30 of the above embodiment.

In addition, the tire conveying devices C and Ca of this embodiment are devices suitable for a tire test system. However, the tire conveyance device of the present invention is not applicable to a tire test system.
